Description
Technical field
The present invention relates to construction material, be specifically related to a kind of outer wall flexible waterproof putty powder and preparation method thereof.
Background technology
Powder of lacquer putty for use on is the one of building and ornament materials, and main component is Pulvis Talci and glue.One layer of white putty on the rough house surface just purchased, the whiteness of usual putty more than 90 fineness more than 330.Putty is used to a kind of base material that wall-surface patching is levelling, lays a good foundation for next step decoration (brush paint wallpaper).Putty is divided into interior wall and exterior wall two kinds, and exterior wall putty to be resisted and to expose to the weather so colloidality is big, intensity is high, and environmental protection index is slightly lower.Inner wall putty aggregative index is preferable, health environment-friendly, so interior wall not external, exterior wall is not interior to be used.Generally putty is Gypsum Fibrosum or cement based, such rough surface be easier bonding firmly.But construction when, also it is intended in basic unit, brush a bed boundary Ji Lai sealing basic unit improves the adhesive force of metope simultaneously, putty can be preferably bonded on basal plane.Existing outer wall flexible putty powder is to be mostly to mix with triple superphosphate, white cement, organic additive etc., and it is mainly used as outer surface of wall alignment material.The quality of exterior wall putty quality directly affects dicoration and the durability of coating ornamental surface; exterior wall putty that serviceability is inferior or inner wall putty external; finally often lead to engineering delivery use the most i.e. occur metope come off, hollowing, cracking; local or Large area coatings lose original decoration and defencive function, have had a strong impact on the normal use of building.The prescription of architectural engineering External Wall putty, is mainly reflected in the indexs such as adhesion strength, initial stage splitting resistance and dynamic cracking resistance, and adhesion strength is one of which important technology index.In construction often poor because of putty product quality, cause putty cannot normally be attached to surface of wall, cause the efflorescence of putty top layer or come off, even peeling, leaving foaming vestige after drying.Existing architectural waterproof material and performance of heat protective material are single, and waterproof is not incubated, insulation non-watertight, and some can not be combined into one with body of wall, and intensity is bad, and cost is high.
Summary of the invention
It is an object of the invention to provide a kind of outer wall flexible waterproof putty powder and preparation method thereof, pure white, exquisiteness, construction workability is good, and intensity is high, water-tolerant, cracking resistance, and concrete technical scheme is as follows:
